Is it worth it..., Magnaflow? Options

[urbandork]

Im slowly thinking about putting a magna flow muffler on my 6th gen. But im wondering is it worth it? Im wondering more about sound then performance but both do matter.

How much diffrence in noise does it make? How much deeper is it?

Also i have a GT if i go for a 2.5 over a 2.25 is there an adapter that i can use to keep the stock piping or would i have to get 2.5 piping all the way from the down pipe and back?

Whats the stock size for GT piping n e one know?

Ive search the forum and found that when it comes to muffler suggestions its the magnaflow or flowmaster. Ive been told that magnaflows are better. Is this true or a simple bias?

I have a question... When i bring my car to the exhaust shop I will have to bolt up my mani and turbo so he can make a downpipe and 2.5 all the way back to a magnaflow muffler.. But i cant drive it home liek that because the turbo isnt all hooked up.. What will they do so i can put my stock mani back on and drive home like i jsut got an exhaust done??? Also i think this place only does crush bends.... and its the only one around here so i think i have to do crush
